EPM5064JC-2 概述
A programmable logic device (PLD) is a digital integrated circuit whose logic function and interconnect are defined by the user after manufacture, replacing multiple discrete TTL/CMOS glue-logic gates with a single reconfigurable chip. Within the broader semiconductor hierarchy, a PLD sits between simple 74-series logic ICs and a full FPGA: it offers deterministic timing, non-volatile (UV-erasable) configuration, and a Product-Term Array interconnect - making it ideal for state-machine, decoder, and bus-interface glue logic on legacy 5 V boards.
Key features of the EPM5064JC-2 include four Logic Array Blocks (LABs) interconnected through the Altera Programmable Interconnect Array (PIA), CMOS technology for low power consumption, and a one-time-programmable-with-UV-erase architecture that historically supported iterative design cycles in 1990s industrial, telecom, and military prototyping. The MAX 5000 family was one of Altera's first commercial MAX architectures and the direct ancestor of the later MAX 7000/3000A series.
The internal architecture uses an EEPROM/EPROM-style configuration cell plus a classic AND-OR sum-of-products macrocell; outputs can be registered or combinatorial, and each macrocell includes a programmable flip-flop, XOR gate for polarity control, and a tri-state buffer for bidirectional I/O. The -2 speed grade corresponds to the slower of the two commercial grades offered for the MAX 5064 die, trading some clock speed for lower cost and higher yield.
Typical applications include legacy glue-logic replacement on VME/ISA backplanes, industrial 5 V control boards, military prototyping using MIL-STD-883B ceramic parts, address decoding for microcontroller memory maps, and bus-interface arbitration. Engineers still spec the EPM5064JC-2 today when maintaining long-lifecycle 5 V equipment such as avionics LRUs, CNC controllers, and telecommunications line cards.
When designing with this device, remember that UV erasure requires a 30-60 minute quartz-window exposure to ultraviolet light - it is NOT in-system reprogrammable. For new designs requiring similar macrocell density with ISP, use the modern MAX 3000A or MAX V (5 V tolerant) family.

典型应用
EPM5064JC-2 适用于 6 应用s: Legacy 5V Glue Logic Replacement, VME/ISA Bus Address Decoding, Military/Aerospace Sustainment, CNC & Industrial Machine Controllers, Telecom Line-Card Glue Logic, Industrial Test & Measurement Equipment.
Legacy 5V Glue Logic Replacement
The EPM5064JC-2 is purpose-built for legacy 5V glue-logic replacement on industrial, telecom, and military boards. Its 64 macrocells and 28 I/O pins can replace 4-8 discrete 74LS/74HC TTL packages, while its 45 ns propagation delay matches typical 74LS138/139 decoder timing. Unlike a discrete gate array, the MAX 5064 architecture lets engineers re-program the logic via UV erasure during prototyping, accelerating board bring-up. The single 5V VCC (4.75V-5.25V) matches the standard TTL supply rail, eliminating level shifters. Use the EPM5064JC-2 to consolidate scattered decoders, multiplexers, and state machines into one ceramic-windowed PLD that can be re-erased and re-programmed as the design evolves.
推荐
VME/ISA Bus Address Decoding
The EPM5064JC-2 is a workhorse for VME and ISA backplane address-decoding applications in industrial PCs and legacy telecom line cards. Its 7 dedicated inputs comfortably capture a 24-bit VME address bus (using only the high-order bits per bank) or a 16-bit ISA address bus, while 28 bidirectional I/O pins drive chip-select signals for memory, I/O peripherals, and DMA controllers. The deterministic 45 ns propagation delay is well below the 90 ns ISA bus cycle time, leaving ample margin for the Programmable Interconnect Array's worst-case routing. Engineers use this PLD to consolidate 6-10 PAL/CEPL chips into a single ceramic part that survives the 0C-70C commercial envelope typical of card-cage environments.
推荐
Military/Aerospace Sustainment
The EPM5064JC-2 in its ceramic-windowed CLCC package supports MIL-STD-883B screening variants (EPM5064DM/883B) for military and aerospace sustainment programs. The UV-erase window enables field updates via reprogramming at depot-level maintenance, while the ceramic J-lead package withstands thermal cycling and vibration per MIL-STD-202. Its 64 macrocells and 7 dedicated inputs implement the kind of moderate-density state machines and bus-arbitration logic found in avionics LRUs, missile telemetry, and radar signal-conditioning modules. The 5V supply is compatible with legacy MIL-STD-1553 transceivers and discrete analog front-ends, eliminating the need for level translation.
推荐
CNC & Industrial Machine Controllers
Long-lifecycle CNC machines, PLCs, and motion controllers from the 1990s still spec the EPM5064JC-2 for stepper-motor sequencing, encoder decoding, and limit-switch arbitration. Its 45 ns tPD comfortably drives 1-2 MHz step pulse trains, while 28 I/O pins interface to optocouplers, Hall-effect sensors, and H-bridge drivers without external latches. The ceramic-windowed package tolerates the 0-70C industrial enclosure temperature range and the high-vibration environment typical of factory-floor equipment. Service engineers keep spare EPM5064JC-2 units on hand because the original Altera tooling (MAX+PLUS II + EPROM programmer) is still operational in many repair depots.
推荐
Telecom Line-Card Glue Logic
The EPM5064JC-2 is a legacy building block in telecommunications line cards, implementing T1/E1 framer interface logic, HDLC controller glue, and time-slot assignment decoders. Its 64 macrocells and 28 I/O pins support the kind of moderate-density glue between a framers ASIC, a DSP, and a backplane transceiver typical of 1990s-class central-office equipment. The deterministic MAX 5000 architecture guarantees no metastability surprises in the routing fabric - critical for telecom applications that must pass Bellcore GR-1089 surge and emissions tests. New telecom designs use modern FPGAs, but sustainment of legacy Class-5 switches still depends on the EPM5064JC-2.
推荐
Industrial Test & Measurement Equipment
Bench-top and rack-mount test & measurement instruments from the late 1990s - oscilloscopes, spectrum analyzers, function generators - integrated the EPM5064JC-2 for trigger logic, timing generators, and front-panel switch decoding. The 45 ns tPD is well below the typical 100 MHz analog front-end bandwidth, so the PLD never becomes the bottleneck. Its 7 dedicated inputs handle trigger-level comparators and external synchronization, while 28 I/O pins drive relays, attenuators, and LED status indicators. The 5V supply matches the op-amp and comparator rails of legacy analog signal paths, simplifying board partitioning. Service manuals for HP/Agilent 54600-series oscilloscopes and similar instruments still reference the EPM5064JC-2 as a service part.

设计说明
Do NOT assume the EPM5064JC-2 is in-system programmable (ISP). It uses one-time-programmable (OTP) EPROM cells that require UV erasure through the quartz window for reprogramming. Attempting ISP via JTAG or any 5V/3.3V logic on the I/O pins will not work. Use a Data I/O BP-1200 or equivalent EPROM programmer with the original MAX+PLUS II-generated JEDEC fuse map. Erasure requires 254 nm UV light at 12-15 mW/cm^2 for 30-60 minutes - sunlight through a window can erase the part over several hours.
Estimated: at fMAX 50 MHz with 28 I/O switching at 50 pF load each, the EPM5064JC-2 draws approximately 200-300 mA total from a 5V supply (VCC static current ~20 mA plus dynamic CMOS switching current of ~8 mA per MHz at full load). For 5V/2A designs, a local 10 uF tantalum + 0.1 uF ceramic decoupling network placed within 25 mm of the VCC pin is essential to suppress switching noise that would otherwise corrupt the 45 ns timing margins. The MAX 5000 family datasheet (per Altera) recommends a minimum 1 uF bulk capacitor plus per-pin 0.1 uF ceramic.
The 28-pin CLCC (J-lead ceramic) package requires a socket or land pattern with castellated J-lead pads. Do not design a board that expects the plastic-windowed JEDEC-20 PLCC footprint - the CLCC ceramic body is slightly larger (0.95 mm lead pitch vs 1.27 mm PLCC). When laying out the PCB, keep all 28 traces short and matched within 5 mm to minimize propagation-delay skew, and reserve a guard ring around the package for the 5V-to-GND decoupling network. The quartz erase window on top of the package requires 5 mm vertical clearance to allow UV erasure without removing the part.
When interfacing the EPM5064JC-2 to high-speed buses (e.g., a 33 MHz VMEbus or a 25 MHz ISA bus), add 22-33 ohm series damping resistors on clock and bidirectional I/O lines to suppress transmission-line ringing on the 45 ns-edge transitions. The MAX 5000 family output drive strength is approximately 24 mA (per Altera datasheet) - high enough to drive 50 ohm transmission lines but low enough that a poorly-terminated line will ring for 2-3 cycles. Place damping resistors within 25 mm of the driver pin.
